int main() { map mp; map::iterator it, it1; int choice; string author, title; while (1) { cout<<" ---------------------"<>choice; switch(choice) { case 1: getchar(); cout<<"Enter Author Name to be inserted: "; getline(cin, author); cout<<"Enter Book Title to be inserted: "; getline(cin, title); mp.insert (pair(author, title)); break; case 2: getchar(); cout<<"Enter Author Name to be deleted: "; getline(cin, author); it=mp.find(author); if (it != mp.end()) { cout<<"Element found and deleted"<

break; case 5: cout<<"Size of the Map: "< "<<(*it).second<

When I input choice with some letters such as "p" "af" ...like that, this program will be endless loop. How can I fix it?

Thank you1
